I don't buy it. Nancy Pelosi has too much baggage to be a successful presidential candidate, i.e., her record. She will not play well in Peoria at all, at all. She is also Catholic, which I think is still a handicap for a presidential candidate. Furthermore, the Clintons still run the Party.
However, she may very well be Hillary's running mate in 2008. This is something to be feared. You heard it here first.
